According to these figures the relations of these composite 

 flowers to the anthophilous insect-fauna are about the same in 

 both regions, so far as the proportion of short-tonsrued and long- 

 tongued visitors is concerned. There is a somewhat larger per- 

 centage of the latter, and a corresponding smaller percentage of 

 the former in the results from southern Illinois, but whether this 

 is due to a larger percentage of long tongues, and a smaller per-
